This chair is really comfortable I am glad purchased it.

David Sloan
Wonderful chair

Chair is well made and supports my back very well.

9/10 for me

This review is based on 3 months of using the chair

Here are the pluses

- Super fast delivery (2 days)
- Easy instructions, had to search for the screws ;)
- I love that the armrests can be taken off for when I play guitar
- The chair gives a lot of comfort while working.
- Super friendly customer service! Thanks for that

Here are the cons

- I personally would have liked some other colors
- It doesn't feel comfortable enough to really take a nap on

For me, it really is a big 9/10, especially for the price. Very neat!

If you are hesitating to buy another chair, I would definitely buy this one! Haven't regretted it for a moment.

Robert Lanktree
Did not disappoint

Nicely made chair, arrived very close to the time given. Well packaged, not difficult to assemble and included instructions. I like that most the hardware was attached to the chair itself, very efficient. After a few days of use it's a comfortable attractive chair that's decent value for cost.

Buck Wheat Johnson
Shocking !

Totally 100% shocked at the weight & quality of this chair. That is shocked in a very good way, it's amazing. The quality & engineering of this chair far exceeded my expectations. I would highly recommend this product to anyone that spends much time at a computer. Excellent product, thanks Onyx !

Scott Slobodian
Repair the manual

Guys, The chair is very nice BUT the directions book is awful. I looked all over for the screws and finally found them installed already. There are also no washers as listed.
